Filament Spool Wall Bracket

thingiverse

I'm creating a system to organize my printer closet using 3/8" rod or tubing that can expand or contract as needed. It's ideal to use roller bearings or slotted rollers, but printable rollers are also included for an economical option. In reality, spools will roll just fine on the bare rods without any additional support. This system should hold all commercial spool sizes with ease.
